Abstract
Northwestern University is one of three university centers participating in a coordinated program of research and education directed toward solving the complex problems of amputees. Major improvements in artificial limbs have been made in recent years. Some of the modern devices are illustrated. A physician who accepts an amputee or a potential amputee for a patient assumes responsibility for maximal restoration, including participation in prescription of a prosthesis and supervision of training. The amputee is permanently in need of qualified medical supervision.
